Description
Technical field
The invention belongs to a kind of method of making aspheric grating that relates in the spectral light gate technique field.
Background technology
Concave grating has the self-focusing characteristic, does not need collimating optical system and Focused Optical system can form spectral line when imaging.Aspheric grating is used for spectrometer system to have than concave grating superior characteristic more, can utilize the grating face shape of aspheric grating to adjust the aberration of spectrometer system.
Use aspheric grating can reduce the aberration of optical system, the size of dwindling spectral instrument reduces the amount of parts of forming, and improves image quality, resolving power and the measuring accuracy of spectral instrument.Therefore, aspheric grating becomes the indispensable optical element of development spectral technique.
The making of motherboard aspheric grating has the processing technology complexity, fabrication cycle is long, production efficiency is low, processing cost is high and shortcoming such as repeatable difference.At present, we do not find the method that adopts reproduction technology to make aspheric grating, adopt the epoxide-resin glue reproduction technology to produce aspheric grating and can dwindle fabrication cycle, enhance productivity, reduce cost.
Summary of the invention
The objective of the invention is to reduce cost, enhance productivity, propose a kind of new, cheaply, the aspheric grating that is easy to the realize new method of duplicating.
The technical problem to be solved in the present invention is: a kind of method that adopts reproduction technology to make aspheric grating is provided.The technical scheme of technical solution problem is: the selection of the first step, motherboard aspheric grating; Select the surface not have flaw, motherboard aspheric grating that diffraction efficiency is high, because any defect on surface all can embody on the aspheric grating after duplicating; The selection of second step, substrate comprises the selection of copy board substrate and daughter board substrate; Selection principle is as follows: the motherboard aspheric grating is a concave spherical surface, the copy board substrate should be selected protruding sphere, and the protruding sphere of copy board substrate and the concave spherical surface of motherboard aspheric grating are during relative the coupling, contact around two faces, center section separates, and can make the epoxide-resin glue between grating concave spherical surface and the copy board substrate can retain like this; The 3rd step, manufacturing replica board non-spherical grating, comprise that plating separates oil film, the aluminium film, bonding, curable adhesive layer, as shown in Figure 1, motherboard aspheric grating 1 is put into vacuum coating equipment plate separation oil film 2 and aluminium film 3 respectively, after taking out motherboard aspheric grating 1 epoxide-resin glue is coated on the aluminium film 3 of motherboard aspheric grating 1, form epoxy glue layer 4, then copy board substrate 5 is separated oil film 2 with having, motherboard aspheric grating 1 bonding of aluminium film 3 and epoxy glue layer 4, putting into 63-67 ℃ of drying box then solidifies, be 4-5 hour set time, scraping off with blade then accumulates in around motherboard aspheric grating 1 and copy board substrate 5 bonding parts and epoxide-resin glue that the Chamfer Edge place has cured, copy board substrate 5 after solidifying is separated with the cohesive body of motherboard aspheric grating 1, carry out with blowing up a balloon to obtain copy board aspheric grating 6 after the cleaning; The 4th step, manufacturing daughter board non-spherical grating, as shown in Figure 2, copy board aspheric grating 6 is put into vacuum coating equipment plate separation oil film 7 respectively, aluminium film 8, after the taking-up epoxide-resin glue is coated in and forms epoxy glue layer 9 on the aluminium film 8 of copy board aspheric grating 6, then daughter board substrate 10 is separated oil film 7 with having, copy board aspheric grating 6 bondings of aluminium film 8 and epoxy glue layer 9, putting into drying box then solidifies, solidification temperature is 63-67 ℃, be 4-5 hour set time, scraping off with blade then accumulates in around copy board aspheric grating 6 and daughter board substrate 10 bonding parts and epoxy glue layer 9 that the Chamfer Edge place has cured, daughter board substrate 10 after solidifying is separated with the cohesive body of copy board aspheric grating 6, carry out with blowing up a balloon can obtaining daughter board non-spherical grating 11 after the cleaning, this daughter board non-spherical grating 11 is exactly and 1 identical aspheric grating of shape of motherboard aspheric grating.
Principle of work of the present invention explanation: utilization epoxide-resin glue replica method, take vacuum evaporation to separate oil film and use the technology of epoxy resin glue bond, the aspheric grating by copying that is not easy to make is made.
Good effect of the present invention is: employing replica method that the present invention mentions make aspheric grating be novel, cheaply, be easy to realize, save cost widely, shortened the fabrication cycle of aspheric grating, utilize the inventive method can produce lower-cost all kinds of aspheric grating, this method can be used to produce in batches aspheric grating.
